I have two 12mm wheel spacers and two 15mm wheel spacers complete with 20 extended lug bolts for sale. These were purchased from Burger Tuning and they are hubcentric 72.5mm black anodized aluminum spacers. The lug bolts are aircraft grade 10.9. All in perfect condition. Price $150 plus shipping for all 4.

I used them on my 135i with M sport package and had no rubbing issues at all.
